I am so confused. I got my usual period zit a couple of days ago and then my temp fell on Tues so I expected AF to show. Well yesterday temp went up and today up a little more. As soon as I got out of bed this AM I felt what I thought was AF. Sure enough I had started spotting which usually lead right into AF but it started out reddish pink then the rest of the day has been brown

It has lasted all day the spotting so I still can't count it as CD1 right

???
UPDATE-
I have had a little heavier than red spotting all day and my temp dropped a bit so I'm gonna assume AF is here and just light
Maybe it has something to do w/ the biopsy???
